[Normativity of overview report of the systematic review of acupuncture and moxibustion at home and abroad based on PRIO-harms scale].

OBJECTIVE: To evaluate and compare the normativity of overview report of systematic review (Overviews) of acupuncture and moxibustion at home and abroad so as to further improve the report quality of Overviews of acupuncture and moxibustion in China and provide reliable evidences. METHODS: The articles relevant with Overviews of acupuncture and moxibustion at home and abroad were retrieved by computer from the databases of CNKI, VIP, Wanfang, China BioMedical Literature database (SinoMed), PubMed, Embase and Conchrane Library, dated from the time of establishment to February 12, 2019. The preferred reporting items for Overviews (PRIO-harms) was adopted to evaluate their normativity and make the comparison of the articles between China and foreign countries. RESULTS: A total of 13 articles of Overviews of acupuncture and moxibustion were included, 9 articles of them were of Chinese version and the rest were of English version. The results of PRIO-harms indicated that the proportions of the item numbers related to adequate, partial and inadequate adherence of Chinese version were 3.7%, 63.8% and 32.5%, and those of English version were 12.0%, 57.4% and 30.6% respectively. The reports on the item 10 "additional search for primary studies", the item 12 "data items" and the item 26 "Dual/(co-)authorship" were inadequate adherence by 100% in the articles of both Chinese and English version. CONCLUSION: The overall information of English article report is better than Chinese one, but the reports of either Chinese or English articles are not so satisfactory. It is suggested that the Overviews report should be in reference to the specification in PRIO-harms and the Chinese researchers should study the advantages of English article report and improve the normalization and report quality so as to obtain the high-quality evidences in evidence-based medicine.

The Role of MicroRNAs in the Pathogenesis of Diabetic Nephropathy.

Diabetic nephropathy (DN) is one of the most common microvascular complications in diabetic patients; it is also an important cause of renal dysfunction, renal fibrosis, and end-stage renal disease. Unfortunately, the pathogenesis of DN is complex and has not yet been fully elucidated; hence, the pathogenesis of DN to determine effective treatments of crucial importance is deeply explored. Early DN research focuses on hemodynamic changes and metabolic disorders, and recent studies have shown the regulatory role of microRNAs (miRNAs) in genes, which may be a new diagnostic marker and therapeutic target for diabetic nephropathy. In this review, we summarize the recent advances in the clinical value and molecular mechanisms of miRNAs in DN, providing new ideas for the diagnosis and treatment of DN.

[Construction of an eukaryotic expression plasmid for AY358935 gene].

OBJECTIVE: To construct an eukaryotic expression plasmid for AY358935 gene and explore its function. METHODS: cDNA of the AY358935 gene was amplified by reverse transcription-PCR and cloned into pGEM-Teasy. The pGEM-T-AY was validated by sequencing and served as a template for the construction of eukaryotic expression plasmid. The pcDNA3.1-AY recombinant was validated by double enzyme digestion and used for transient transfection of M14 cells. Expression of the AY358935 protein and proliferation of the M14 cells were determined respectively by Western blotting and 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) colorimetry. RESULTS: The amplicons of RT-PCR were confirmed to have similar size with the cDNA fragment of the AY358935 gene as well as cloned region of pcDNA3.1-AY. The cloned region of pGEM-T-AY was sequenced to be identical with cDNA sequence of the AY358935 gene. M14 cells were transfected by the AY358935 gene, pcDNA3.1 and liposomes, respectively. After 48 h, expression of the AY358935 protein in M14 cells transfected with the AY358935 gene was significantly higher than other two groups. They also had a significantly higher absorbance value (A=0.74) than other two groups (A=0.39 and 0.46, respectively; P<0.05). CONCLUSION: An eukaryotic expression plasmid of the AY358935 gene was successfully constructed. Product of the AY358935 gene may promote the proliferation of M14 cells.
